When sending PC messages to Astrolab, the UI doesn’t go into Playlist/Songlist/Preset (yellow mode). Instead it stays in normal (blue mode), but mimics the button usage.
ie, Piano, E-Piano, Organ … &/or arrows choose the Song as if it was still in Songlist (yellow mode), but no onscreen visualisation indicates that Playlist mode has been activated.
Additionally, the Category pop-down incorrectly shows what ever was the last chosen Preset’s category (before PC msg was received) any time the Song Preset is changed.
Exiting back to Main menu fixes this until next PC is received.
I feel that when a PC message is received, Astrolab should change UI to Playlist (yellow) mode on both LCD screen and buttons, as this would make it unambiguous to the current operational state, and also allow quick exit by pressing (yellowed) Playlist button to return to Preset browser.
